VOB to AVI Converter

How to Convert VOB to AVI Online

1. Upload Your VOB Files: Click "+ Add Files" or drag and drop VOB files — usually copied from the VIDEO_TS folder of a DVD. The DVD-Video spec splits content into 1 GiB chunks (VTS_01_1.VOB, VTS_01_2.VOB, etc.), so upload them all together to keep the program intact. Batch upload supported.
2. Pick Quality Preset (or Bitrate / Constant Quality): Default is Very High (Recommended). Choose Highest / High / Medium / Low / Lowest for one-click control, or switch the compression mode to Constant Bitrate, Variable Bitrate, Constant Quality, or Constraint Quality for fine-grained tuning. Set Video Codec (Xvid, DivX, MPEG-4, MPEG-2, H.264, MJPEG, HuffYUV) and Audio Codec (MP3, AC-3, PCM, MP2) — Xvid or DivX gives you classic AVI compatibility, MPEG-2 + AC-3 with the Copy behavior keeps the DVD streams untouched.
3. Resize, Trim, Set Resolution (Optional): Pick a Preset Resolution (4320p down to 144p, plus DVD-native 720x480 / 720x576), use Resolution Percentage, or enter custom Width x Height (Keep aspect ratio toggle). Switch Trim from Unchanged to Time Range to clip out menus, FBI warnings, or trailers before encoding.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no DVD ripping software to install.

Why Convert VOB to AVI?

VOB (Video Object) is the MPEG program stream container used on every DVD-Video disc since the format launched in 1996. It carries MPEG-2 video plus AC-3, DTS, LPCM, or MP2 audio, and is capped at 1 GiB per file so feature-length movies are split across multiple .VOB files inside the VIDEO_TS folder. AVI (Audio Video Interleave, released by Microsoft on November 10, 1992 as part of Video for Windows) is a more flexible RIFF container that holds a far wider codec range and is what most legacy NLEs, older media players, and embedded systems expect.

• Editing in legacy NLEs — Sony Vegas, older Premiere Pro builds, Pinnacle Studio, and Windows Movie Maker all import AVI cleanly but choke on VOB's program-stream layout. Re-wrapping with Xvid or DivX produces an AVI that any DV-era editor can scrub frame-accurately.
• Bypassing DVD navigation — Raw VOB files only play correctly inside the full VIDEO_TS directory structure with companion IFO and BUP files. Converting to a single AVI strips out the chapter/menu/multi-angle navigation so you get one continuous file.
• Joining the 1 GiB chunks — DVD spec slices the main feature into VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB… AVI has no such per-file cap (FAT32 imposes 4 GiB, NTFS/exFAT effectively unlimited), so the whole movie becomes one file.
• Old hardware playback — Many 2000s-era DivX-certified DVD players, in-car head units, and PMPs (Archos Jukebox, iRiver PMP-100) play AVI/Xvid but cannot mount a VOB without the surrounding DVD folder.
• Long-term archival — Pairing the MPEG-2 stream with the HuffYUV lossless codec or simply Copy-muxing it into an AVI container preserves bit-for-bit DVD quality on a hard drive while shedding the proprietary DVD layout.
• Compressing for storage — A typical 4.7 GB single-layer DVD reduces to 700 MB-1.5 GB at Xvid 1500 kbps with negligible perceptual loss, freeing terabytes when archiving a disc collection.

Frequently Asked Questions

Should I rip my DVD to AVI, MP4, or MKV?

AVI only if your target software is older than ~2010 (legacy Vegas, Premiere Pro CS3/CS4, Pinnacle, DivX-certified set-tops). For modern playback or streaming, convert to MP4 with H.264 — smaller files, hardware-accelerated decode on every phone and TV, native subtitle support. MKV is the best choice when you need multiple audio tracks, chapter markers, and soft subtitles from the DVD all in one container.

Why are my VOB files split into multiple parts and should I join them first?

The DVD-Video spec caps each VOB at 1 GiB for filesystem compatibility (UDF / ISO 9660), so a 90-minute feature is typically split into VTS_01_1.VOB through VTS_01_4.VOB. Upload all of them together — the converter concatenates the MPEG program stream in order before re-muxing, so you get one continuous AVI rather than four chunks. Concatenation itself is lossless; only the AVI re-encode introduces quality change.

Will subtitles, multiple audio tracks, and chapters carry over?

No. DVD subtitles are VobSub bitmap streams stored alongside the video; AVI has no native subtitle support per the Microsoft RIFF spec, so they're dropped during conversion. Multi-channel AC-3 audio is preserved if you keep the AC-3 audio codec, but only one track survives — AVI doesn't reliably handle multiple audio streams in older players. Chapter markers and DVD menus are encoded into IFO files, not VOB, so they're discarded.

Does this tool break DVD copy protection (CSS)?

No. xconvert processes the VOB files you upload — if your DVD has CSS encryption, the VOB data on disc is scrambled and you must decrypt it first with a tool like MakeMKV or HandBrake before uploading. Once VOB files are unencrypted (your own home video DVDs, public-domain releases, or already-decrypted rips), this converter handles them normally. Check your local copyright laws before ripping commercial DVDs.

What's the best codec choice for a DivX-certified DVD player?

Xvid at 1500-2000 kbps with MP3 or AC-3 audio, resolution capped at 720x480 (NTSC) or 720x576 (PAL), keyframe interval ~10 seconds. Most DivX Home Theater profile players (Philips, LG, Samsung 2005-2010 era) require Xvid Simple or Advanced Simple Profile and reject H.264-in-AVI. Set Video Codec to Xvid and pick the matching DVD resolution from the Preset Resolutions dropdown.

Can I trim out the FBI warning or DVD menu loops before converting?

Yes. Switch the Trim control from Unchanged to Time Range and enter start/end timestamps in HH:MM:SS.mmm format. Most commercial DVDs front-load 30-90 seconds of unskippable warnings, studio logos, and trailers before the feature — set start time to where the actual content begins to skip them in the AVI output.

Why is my AVI bigger than the original VOB?

If you chose a lossless codec (HuffYUV) or a high bitrate constant-bitrate setting, AVI re-encoding can balloon past the MPEG-2 source. VOB's MPEG-2 is already a fairly efficient compressed format at DVD bitrates (~6-9 Mbps). To shrink: pick Xvid/DivX with Variable Bitrate at 1200-1800 kbps target, or use Constant Quality with a CRF in the mid-range. The MJPEG and HuffYUV options are intentionally larger because they're designed for editing intermediates, not delivery.

Can I extract just the audio from a VOB instead of converting the video?

Yes. Use VOB to MP3, VOB to AC3, or VOB to WAV — these pull only the audio stream so you can grab commentary tracks, soundtracks, or concert audio without re-encoding video. AC-3 preserves the original Dolby Digital surround mix bit-for-bit if you pick Copy behavior. To shrink an existing VOB without changing format, use Compress VOB; to clip a section before conversion, Trim VOB.

Will the converted AVI play on Windows Media Player and VLC?

VLC plays everything — every codec listed above works without extra plugins. Windows Media Player on Windows 10/11 plays Xvid, MPEG-4, and H.264 AVI natively; MPEG-2-in-AVI may need the K-Lite Codec Pack or a separate MPEG-2 decoder license. For maximum out-of-the-box compatibility, pick Xvid video + MP3 audio — that combination has worked in WMP since Windows XP.
